Help please I'm stuck on this question

120 yd²

Step-by-step explanation:

The floor consists of a square and a triangle

area of square = 10² = 100 yd²

area of triangle = bh ( b is the base and h the height )

Here b = 4 and h = 10 , then

area = × 4 × 10 = 2 × 10 = 20 yd²

company needs 100 + 20 = 120 yd²

i think that you should ask google for the answer to that problem because if we don't know it google does

6 adults and 9 children went.

a + c = 15

12a + 9c = 153

12(6) + 9(9) = 153

72 + 81 = 153
