Question

10. Find the area of the shaded region.

17 yd
5 yd
7 yd
6 yd
7 yd
4 yd

Answer 1

176 yd

Explanation:

UNSHADED REGION (white rhombus): A=(s1+s2)/2 * H

s1=7

s2=1+7=8

H=6

A=(7+8)/2*6=45

SHADED + UNSHADED REGION (big parallelogram): area of parallelogram A=B*H

B=17

H=7+6 = 13

A=17*13=221

SHADED REGION: big parallelogram area - rhombus area

221 - 45 =176 yd
