Question

a playground is 30 metre long and then it is wide if its perimeter is 300 metre what is the area​

Answer 1

$\huge\mathcal{\purple{A}}{\mathcal{\green{N}}}{\mathtt{\pink{S}}}{\mathcal{\blue{W}}}{\mathcal{\purple{E}}}{\mathcal{\green{R}}}{\pink{!}}{\blue{!}}$

Length (l) = 30m

breadth (b) = ?

Area = ?

Perimeter = 300m

Perimeter = 2(l+b)

=> 300 = 2(30+b)

=> 300/2 = 30 + b

=> 150 = 30 + b

=> b = 120m

Area = length × breadth

⠀⠀⠀ = 30 × 120

⠀⠀⠀ = 3600 sq. m
