Answer:
49.5 square inches
Step-by-step explanation:
We can split the figure into two easier shapes to find the area of; a triangle and a square.
The formula for a triangle is (b*h)1/2. Once we solve we get 24.5 or 24 1/2.
The formula for a square is l*w. Once we solve we get 25.
To find the area of the shaded region, we would add both area and get 49.5 or 49 1/2 square inches.
The money Debra has is $ 316.66
<em><u>Solution:</u></em>
Let the amount with Debra be "x"
Let the amount with Sherry be "y"
<em><u>Given that Debra and Sherry have 475 in total</u></em>
Amount with Debra + Amount with Sherry = 475
x + y = 475 -------- eqn 1
<em><u>Debra has twice as much money as sherry</u></em>
Amount with Debra = 2(amount with sherry)
x = 2y ------- eqn 2
<em><u>Let us solve eqn 1 and eqn 2</u></em>
<em><u>Substitute eqn 2 in eqn 1</u></em>
2y + y = 475
3y = 475
Divide both sides of equation by 3
y = 158.33
<em><u>Substitute y = 158.33 in eqn 2</u></em>
x = 2(158.33)
x = 316.66
Thus Debra has $ 316.66
