Question

Find the area of the figure below (sides meet at right angles)

Answer 1

d² + df + dg + dh = d(d + f + g + h)

Explanation:

Lower rectangle:

length = f + d + h

width = d

Upper rectangle:

length: d

width: g

total area:

d(f + d + h) + dg =

= df + d² + dh + dg

= d² + df + dg + dh

= d(d + f + g + h)
