Question

The length of a rectangular pond is 15 m less than twice of its width.If the perimeter of the pond is 330m, find its area​

Answer 1

Perimeter of pond(rectangle)=2(l+b)

330m=2(15+b)

330/2=(15+b)

165m=(15+b)

165-15=b

150m=b

Answer 2

Step-by-step explanation:

2(2x-15+x)=330

4x-30+2x=330

6x=330+30

6x=360

x= 360/6

x=60

Therefore length =60m

Breadth= 2(60)-15= 120-15= 105m

ATQ,

AREA OF RECTANGLE= lxb

60x105=6300m²
