Answer:
91 in²
Step-by-step explanation:
Area of tarpezoid = (sum of both bases x height) / 2
A = ((11 + 15) x 7) /2 = 91
Answer: 91 in ²
This has to be answered in three parts:
1) Area of square
2) Area of triangle
3) Addition of both areas
Let’s start with step one: area of square. The easiest way to solve this sort of equation is by breaking the shape into two easier shapes and finding the area of both. I have attached an image below of how we will separate these shapes
Let’s find the area of the square.
Step 1) Write formula
l • w = a
Step 2) Fill in information and solve
7 • 11 = 77
That’s the area of the square! Now let’s move onto the triangle
Step 1) Write formula
1/2(b•h)
Step 2) Fill in information and solve
(Though it doesn’t say the base, we can find this by subtracting 15 and 11)
1/2(4•7)
1/2 (28)=14
That’s the area of the triangle side! Now let’s add these together for the final answer
Final Step: Finding final area
To find the area of the whole shape, let’s add these two together
Triangle: 14
Square:77
14+77=91
