Question

(i) The perimeter of a rectangle is 480 cm and its length is 140 cm. Find Its area ​

Answer 1

Answer:

1.4m²

Step-by-step explanation:

Perimeter Of Rectangle= 2(l+b)

480=2(140+b)

240=140+b

240-140=b

100cm=b

100cm=1m

So, l=1.4m

l=1.4m b=1m

Area of Rectangle=l×b

= 1.4×1

= 1.4m²
