Question

the following figure is made of 1 triangle and 1 rectangle.
3
10
7
find the area of each part of the figure and the whole figure.
just put the numbers!

figure	area (square units)
rectangle b
whole figure

Explanation:

Step1: Calculate Triangle A height

Height = $7 - 3 = 4$

Step2: Compute area of Triangle A

$\text{Area}_A = \frac{1}{2} \times 10 \times 4 = 20$

Step3: Compute area of Rectangle B

$\text{Area}_B = 10 \times 3 = 30$

Step4: Compute total area

$\text{Total Area} = 20 + 30 = 50$

Answer:

Figure	Area (square units)
Rectangle B	30
Whole figure	50
