Table Of Content
A. 47 cm2
B. 34 cm2
C. 40 cm2
D. 64 cm2
Answer : C. 40 cm2
Explanation 1:
Area of triangle formula = 1/2*(base)*(height)
Area of one triangle = 1/2 * (4) * (5)
= 10 cm2.
Total area of rhombus = 4 * area of one triangle
= 4 * 10
= 40 cm2
Explanation 2:
Area of a rhombus is = 1/2 * (length of one diagonal) * (length of another diagonal)
= 1/2 * 8 * 10 cm2
= 40 cm2
