I saw the image that accompanied this problem.
4 identical isosceles trapezoid forming 2 parallelogram.
1 parallelogram has a base of 16 inches and its height is 10 inches.
We need to get the area of the parallelogram and multiply it by 2 before dividing it into 4 to get the area of each isosceles trapezoid.
Area of a parallelogram = base * height
A = 16 in x 10 in = 160 in²
160 in² x 2 parallelogram = 320 in²
320 in² / 4 tiles = 80 in²
The area of one tile is 80 square inches.
The area of the triangle based on the information given is 16.67 inches ²
<h3>How to calculate the triangle?</h3>
It should be noted that the area of a triangle is given by the formula:
= 1/2 × base × height
In this second figure, the height will be:
= 5.9² - (3.4/2)²
= 5.9² - 1.7²
= 34.81 - 2.89
= 5.65
The area will be:
= 1/2 × base × height
= 1/2 × 5.65 × 5.9
= 16.67 inches ²

Answer:
the answer is D
Step-by-step explanation:
3x-21=x+7
2x-21=7
2x=28
x=14
substitute x for 14
14+7=21
2X14-21+21
