MNPQ is a rectangle. NP is 20 cm and MN is twice of NP. Find the area of Triangle PRS.
Length of MN
= 2 x 20
= 40 cm

Area of Triangle MRS = ¹₈ of Rectangle MNPQ

Area of Triangle RQP = ¹₄ of Rectangle MNPQ

Area of Triangle SNP = ¹₄ of Rectangle MNPQ
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 cm²

Area of Triangle PRS
= ³₈ x 800
= 300 cm²

Answer(s): 300 cm²
