10. If the length and breadth of a rectangle are in the ratio 5:3 and its perimeter is 144 m,
find the area of the rectangle.​

Answer 1

Answer:

1215m²

Step-by-step explanation:

10.) Length = 5x

Breadth = 3x

Perimeter of a rectangle = 2(L+B)

144 = 2(5x+3x)

144= 2*8x

144= 16x

x= 9

Hence Length = 5x=5*9=45

& Breadth = 3x=3*9=27

Area of rectangle = L*B

= 45*27 = 1215m².
