CDEF is a rectangle. DE is 20 m and CD is twice of DE. Find the area of Triangle EGH.
Length of CD
= 2 x 20
= 40 m

Area of Triangle CGH = ¹₈ of Rectangle CDEF

Area of Triangle GFE = ¹₄ of Rectangle CDEF

Area of Triangle HDE = ¹₄ of Rectangle CDEF
Fraction of the rectangle that is unshaded
= ¹₈ + ¹₄ + ¹₄
= ¹₈ + ²₈ + ²₈
= ⁵₈

Fraction of the rectangle that is shaded
= 1 - ⁵₈
= ³₈

Area of the rectangle
= 40 x 20
= 800 m²

Area of Triangle EGH
= ³₈ x 800
= 300 m²

Answer(s): 300 m²

4 m
