If a =7 , find the area of it .

Please give me the answer I have a exam at 12.00

60cm²

Step-by-step explanation:

Area of a rectangle = length x breath

Let,

length (L) = (a-1) cm

breadth (B) = (a+3) cm

Putting the value of a = 7;

we get,

length= 7-1 = 6 cm

breadth= 7+3 = 10 cm

Therefore, area of the rectangle = L x B

= 6 x 10

= 60 cm²

Step-by-step explanation:

Hello!

a= 7

L = 7+3 = 10

l= 7-1 = 6

area:

10*6 => 60cm²
