Sides of three square rooms measure 13 feet each, and sides of two square rooms measure 15 feet each. which expression shows the total area of these five rooms?
a.(3 × 13^2) + (2 × 15^2)
b.(2 × 13^3) + (2 × 15^2)
c.(3 × 15^2) + (2 × 13^2)
d.(3 × 13^2) × (2 × 15^2)

Answer

Find out the  total area of these five rooms .

To prove

Formula

Area of a square = a²

Where a is the side of a square.

As given

Sides of three square rooms measure 13 feet each.

Thus

Area of the Three rooms = 3 × 13²

As given

sides of two square rooms measure 15 feet each.,

Area of two rooms = 2 × 15²

Total area of the five rooms = Area of the Three rooms + Area of two rooms

                                             = 3 × 13²  + 2 × 15²

                                             = 3 × 169 + 2 × 225

                                             = 507 + 450

                                             = 957 unit²

Therefore the total area of the five rooms be 957 unit².

Thus Option (a) is correct.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
