Question

Площадь одного участка земли 215 м. Это на 98 м меньше площади второго участка и на 57 м больше площади третьего. чему равна площадь всех трех участков?

Answer 1

215+98=313- площадь второго участка
215-57=158-площадь третьего участка
215+313+158=686-площадь всех участков

Answer 2

Calculating the Total Area of Three Parcels of Land

To calculate the total area of the three parcels of land, we can use algebraic equations to represent the given information.

Let's denote: - The area of the first parcel as A1 (given as 215 m) - The area of the second parcel as A2 - The area of the third parcel as A3

We are given the following information: 1. The area of the first parcel is 98 m less than the area of the second parcel. 2. The area of the first parcel is 57 m more than the area of the third parcel.

Using the given information, we can set up the following equations: - A1 = A2 - 98 (Equation 1) - A1 = A3 + 57 (Equation 2)

To find the total area of all three parcels, we need to find the values of A1, A2, and A3.

Solving for the Areas of the Parcels

Let's solve the system of equations to find the areas of the three parcels.

From Equation 1: A2 = A1 + 98 (Equation 3)

Substitute Equation 3 into Equation 2: A1 = A3 + 57 A1 + 98 = A3 + 57 + 98 A1 + 98 = A3 + 155 (Equation 4)

Now, we can substitute Equation 4 into Equation 1: A3 + 155 = A2 A3 = A2 - 155 (Equation 5)

Substitute Equation 5 into Equation 2: A1 = A2 - 98 A1 = (A3 + 155) - 98 A1 = A3 + 57

Now, we have a system of equations to solve for A1, A2, and A3.

Calculating the Total Area

To find the total area of all three parcels, we can sum the areas of the three parcels: Total Area = A1 + A2 + A3

Let's calculate the areas of the three parcels and then find the total area.
