Question

Here are two similar rectangles find the area of the largest one

Answer 1

do it yourself loser

Explanation:

loser

Answer 2

40.32 cm²

Explanation:

The area of the small rectangle = 7 × 4 = 28 cm²

Given the ratio of the sides of similar rectangles = a : b , then

the ratio of the areas = a² : b²

Here ratio of sides = 4 : 4.8 = 1 : 1.2

ratio of areas = 1² : 1.2² = 1 : 1.44

Let x be the area of the larger rectangle then by proportion

`(1)/(28)` =
`(1.44)/(x)` ( cross- multiply )

x = 40.32

Area of larger rectangle is 40.32 cm²
