mojhsa [17]
3 feet= 1 yard

16*3= 48 feet.

47.52/48= 0.99

It will cost Brian $0.99 per foot. 

Find the unit rate. 

49.50/50= 0.99

No, it wouldn't. It would be the <em>same price 

0.99=0.99
It doesn't matter which one Brian chose. </em>

I hope this helps!

Answer:

126 square feet

Step-by-step explanation:

The formula for the area of a triangle is ...

A = (1/2)bh . . . . . where b is the base length and h is the height

Here, you have a triangular face that has a base of 6 ft and a height of 14 ft. Its area is ...

A = (1/2)(6 ft)(14 ft) = 42 ft^2

The lateral area of the pyramid consists of 3 such triangles, so the lateral area is ...

LA = 3·(42 ft^2) = 126 ft^2
