Question

length of a rectangle id 10cm more than the breadth.if the area is 144 square cm,find the length and bradth of the rectangle

Answer 1

Answer:

18,8

Step-by-step explanation:

let breadth = x ,length= x + 10

area = 144

x (x + 10) = 144

x^2 + 10x - 144 = 0

x^2 + 18x - 8x - 144 = 0

x(x + 18) - 8(x + 18) = 0

x = -18,8

neglect -18 so x = 8

breadth=8cm,length= 8+10 = 18cm
