Answer:
Step-by-step explanation:
The perimeter is the sum of the side lengths of the shape. Since a square has equal side lengths, each side must be the same. Divide 52/4=13cm. 13cm is the length of 1 side. Area is length times width, and since each side is 13, multiply 13cm*13cm to get the area, which is ,

Answer:
4x^4y + 20x^2y^2 - 28x^3y
Step-by-step explanation:
4xy(x^3 + 5xy - 7x^2)
= 4xyx^3 + 4xy * 5xy - 4xy * 7x^2
= 4x^2y + 4xy * 5xy - 4xy * 7x^2
= 4x^4y + 20x^2y^2 - 4xy * 7x^2
= 4x^4y + 20x^2y^2 - 28x^3y
Answer:
Area: 312
Perimeter: 75
Step-by-step explanation:
Area is l·w
20·16=320
two corners aren't filled
320-9-9=318
Add all the sides for perimeter
17+3+3+13+20+13+3+3=75
