Answer:
Option A (7×3) + 1/2(7×6)
Explanation:
Divide this shape into a square and a triangle
For area of square the formula is
Area = A = L ×W
From shape of square
7 seven boxes are yellow so L=7 and width W=3
A = 7 × 3
For triangle formula is
A = (1/2)bh
A = (1/2)(7×6)
Add them
A = (7×3) + 1/2(7×6)
