Question

find area and perimeter of rectangle whose dimensions are 10 metres and 90 cm​

Answer 1

Answer:

area = l×b

l = 1000cm

b = 90cm

1000× 90 = 90000 cm which is equal to 900meters

perimeter = 2(l+b)

2(1000+90)

2(1090)

= 2,180 cm

= 21.80meters

Answer 2

area = 9msquare

perimeter = 18m

length = 10m

breadth = 90cm = 0•9

Area = l×b

Area = 10 × 0•9

Area = 9m

Perimeter = 2(l+b)

Perimeter = 2(10×0•9)

Perimeter= 18m
