Question

the perimetre of a rectangle is 68m and its length is 24 m find its braeadth area and diagnol

Answer 1

Hi ,

Let l and b are length and breadth

of the rectangle ,

l = 24 m

b = ?

Perimeter = 68m

2( l + b ) = 68

l + b = 32

24 + b = 32

b = 32 - 24

b = 8 m

2 ) area ( A ) = lb

A = 24 × 8

A = 192 m²

3 ) diagonal ( d ) = √ ( l² + b² )

d = √ ( 24 )² + 8²

= √ 576 + 64

= √640

= 8√10 m

I hope this helps you.

Answer 2

$perimeter \: of \: rectngle = 2(l + b) \\ 68 = 2(24 + b) \\ 68 = 48 + 2b \\ 68 - 48 = 2b \\ \frac{20}{2} = b \\ b = 10$
