Atriangle is cut out of a square whose side length is 8 feet. what will be the approximate area, in square feet, of the remaining board?

Area of the remaining board  = 32 square feet .

Step-by-step explanation:

Given : A triangle is cut out of a square whose side length is 8 feet.

To find : What will be the approximate area, in square feet, of the remaining board.

Solution : We have given that square side length = 8 feet.

A triangle is cut out of a square.

Then,  base of triangle is 8 feet.

Height = 8  feet ( same as the side of square )

Area of triangle = .

Area of triangle =  .

Area of triangle = 32 square feet.

Area of square = side * side .

Area of square = 8 *8

Area of square = 64 square feet.

Area of the remaining board = Area of square - Area of triangle.

Area of the remaining board  = 64 - 32.

Area of the remaining board  = 32 square feet .

Therefore,  Area of the remaining board  = 32 square feet .

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.
