Question

find the expression for the area of whose base is four more than twice the height. also finds its value if height of the triangle is 11cm​

Answer 1

Step-by-step explanation:

let height = x

base = 2x+4

Area = x * 2x+4

height = 11 cm

base = 2x+4 = 2*11+4 = 22+4 = 26cm

Area = height * base

Area = 11cm * 26cm

Area = 286cm square
