Answer» Area of triangle = 1/2 * base * height 80x^2 = 1/2102x 80x = 10 x = 10/80 = 1/8 Therefore,Area = 80*(1/8)^2 = 10/8 = 5/4 = 1.25 m^2 Height = 2x = 2/8 = 1/4 =.25 m

Answer»

Area of triangle = 1/2 * base * height

80x^2 = 1/2*10*2x

80x = 10

x = 10/80 = 1/8

Therefore,Area = 80*(1/8)^2 = 10/8 = 5/4 = 1.25 m^2

Height = 2x = 2/8 = 1/4 =.25 m
