Robert needs enough mulch to cover the triangular garden shown below. if one bag of mulch covers 12 square feet, how many bags of mulch does he need to buy?

≈ 6 bags

Step-by-step explanation:

We need to find the area of the triangle

A = 1/2*the base*the height

Here we have:

=> the area of the triangular garden is: A = 1/2*14.1*9 = 63.45 square feet

Because one bag of mulch covers 12 square feet

=> the number of bags he need to buy is:

= the area of the triangular garden / the area of the bag can cover

= 63.45 / 12 ≈5.2875 bags

≈ 6 bags

a is 8.b is 10.c is 10.5. d is -.5

step-by-step explanation:

just minus the smallest number from the biggest.

96 39 cause 135 -96=39 im smart (i used a calculater)
