Answer:
77 ft squared for the first
180 cm square for second
371 yards squared for third
Step-by-step explanation:
1. The formula of a triangle is 1/2bh
So, mutiply 14 by 11, 154. Then, divide by 2 or multiply by 1/2 to get 77.
2. Find the area of the square first, 100. (l*w) Then, find the area of the triangle, 80. (1/2bh) Last, add 80 and 100.
3. Multiply 12 1/2 and 21 1/5 since the parallelogram is the same a a rectangle, to get 371.
