Question

a rectangle of length 12 cm and breadth 7.5 cm

Answer 1

Area=12*7.5=90.0cm^2
Perimeter = 2(12+7.5)=2*29.5=59.0cm




Is that what you are asking???

Answer 2

Heya,

Question is incomplete but I just guess that your question is either find the perimeter of the rectangle or find the area of rectangle. If yes, Here I will give the solution for both.

To find perimeter,

P = 2 (l + b)
P = 2 (12 + 7.5)
P = 2 (19.5)
P = 39cm

To find Area,

A = l × b
A = 12 × 7.5
A = 90cm^2

Hope my answer helps you :)
