Question

Найди площадь ромба,если одна из его диагоналкй равна 28 см,а вторая диагональ на 40% больше первой

Answer 1

Ответ:

156,8 - площадь

Пошаговое объяснение:

28/100 * 40 = 11,2

28 * 11,2 = 313,6

313,6 / 2 = 156,8 - площадь

Answer 2

Finding the Area of a Rhombus

To find the area of a rhombus, we can use the formula:

Area = (d1 * d2) / 2

where d1 and d2 are the lengths of the diagonals of the rhombus.

In this case, we are given that one of the diagonals is 28 cm, and the second diagonal is 40% larger than the first diagonal.

Let's calculate the area step by step:

1. Find the length of the second diagonal: - The second diagonal is 40% larger than the first diagonal, which means it is equal to 1.4 times the length of the first diagonal. - Therefore, the length of the second diagonal is 1.4 * 28 cm = 39.2 cm.

2. Calculate the area: - Using the formula, we can substitute the values of the diagonals into the equation: Area = (28 cm * 39.2 cm) / 2 - Simplifying the equation, we get: Area = 1097.6 cm²

Therefore, the area of the rhombus is 1097.6 cm².
