A tract of land with a bottom 28m wide, baby bottom 12m, height 8m. People hit 40% to build houses. Calculate the area to be used for housing

Area trapezoidal mahr that is:

(28 + 12) x 8 : 2 = 160 (m2)

The area of land for building a house is:

160 : 100 x 40 = 64 (m2)

The acreage of the land is :

(28+122

) x 8 = 160 (m2)

The acreage to build houses is :

160 x 40% = 64 (m2)

(\(\dfrac{28+12}{2}\)) x 8 = 160 (m^{2})

160 x 40% = 64 (m^{2})
