Question

(g) The length of a rectangle is twice its
breadth. If the perimeter is 90 metres, find
the length and breadth of the rectangle.​

Answer 1

Answer:

L=30m, b=15m

Step-by-step explanation:

Perimater of rectangle= 2(l+b)

Perimater of rectangle= 2(l+b)90m=2(2x+x)

90m=2×3x

3x=90÷2

3x=45

X=45÷3

x=15

2x=30

L=30m

B=15m
