Question

Find the breath and the area if perimeter of rectangle is 38 CM and lenth 12 CM

Answer 1

Answer:

Perimeter of the rectangle = 38 cm

Length of the rectangle = 12 cm

Breadth of the Rectangle = $\frac{Perimeter}{2}$ - Length = ( 38/2 - 12 ) cm = 7 cm

Area of the rectangle = Length x Breadth = ( 12 x 7 ) cm² = 84 cm²

Please mark me brainliest.

Answer 2

l=12cm
b=?
Perimeter of rectangle =38 cm



Perimeter of rectangle = 2*(l+b)
38 =2*(12+b)
38 =24+2b
38-24 =2b
14 =2b
14/2=b
7cm=b (Here u have got the breadth of rectangle)



l=12cm
b=7cm
Area of rectangle =?


Area of rectangle =l*b
=12*7
=84 cm^2



Therefore area of rectangle is 84cm^2
