Question

the measures of two adjacent sides of a rectangle are in the ratio of 7 : 5 if the perimeter of the rectangle is 336 cm finds it area​

Answer 1

Answer:

The area of the rectangle = 6860 $cm^{2}$ = 0.686 $m^{2}$

Step-by-step explanation:

The measures of two adjacent sides of a rectangle are in the ratio of 7:5

Let's assume that, the length of the rectangle is 7x

∴ The breadth is 5x

According to the problem:

2(7x + 5x) = 336

=> 24x = 336

∴ x = $\frac{336}{24}$ = 14

The area of the rectangle = (7x)(5x) = 7x14x5x14 =35x196 = 35 x 200 - 35 x 4 = 7000 - 140 = 6860 $cm^{2}$ = 0.686 $m^{2}$
