Answer:
altogether its 42in(squared)
Step-by-step explanation:
Triangle:
1. 13-8=5
2. area of a triangle is 1/2 x l x b
3. Apply so 1/2 x 5 x 4 = 10in(Squared)
Quadrilateral:
1. 13-5=8
2. area of trapezium is (a+b)/2 x h
3. Apply so (8+8)/2 x 4
= 16/2 x 4
=8 x 4
=32in(squared)
Area of quatrilateral all together:
10+32=42in(squared)
