Question

a drawing of an arrow was made using a rectangle and a triangle, as show. what is the area of the arrow in square inches?
17 square inches
40 square inches
52 square inches
61 square inches

Explanation:

Step1: Calculate rectangle area

$A_{rect} = l \times w = 10 \times 4 = 40$

Step2: Find triangle base length

$b = 4 + 1.5 + 1.5 = 7$

Step3: Calculate triangle area

$A_{tri} = \frac{1}{2} \times b \times h = \frac{1}{2} \times 7 \times 6 = 21$

Step4: Sum both areas

$A_{total} = A_{rect} + A_{tri} = 40 + 21$

Answer:

61 square inches
