Mariam is making
ira [324]

Answer:

  no

Step-by-step explanation:

A trapezoid is shown, not a bag. If we assume that this shape is supposed to be the front of the bag, Mariam does NOT have enough pink fabric to make the front of the bag from pink fabric.

The area of the trapezoid shown is ...

  A = (1/2)(b1 +b2)h

  A = (1/2)(9 in + 8 in)(15 in) = 127.5 in^2

This area is larger than the amount of fabric Mariam has, so she does not have enough.

48 is the perimeter, all sides in a square are equal, you take 12 * 4 which gives you 48.

For the area, you take two sides, length and width, and you multiply them, 12 * 12, this gives you 144.
