1. You have that:

- The trapezoids are similar.
- The larger base of the smaller trapezoid is 18 m and its area is 310 m².
- The larger base of the larger trapezoid is 32 m.

2. Then:

Sides=18/32
Sides=9/16

Area=(9/16)²
Area=81/256

3. Now, you can find the area of the larger trapezoid, as below:

81/256=310/x
81x=(310)(256)
x=79360/81
x=980 m²

Therefore, the answer is: The area of the larger trapezoid is 980 m².

Mark save $258 more than Neil. In fact Mark saved $7 for every $4 Neil saved. How much money did Mark say?

Let

x---------> amount of money saved by Mark

x---------> amount of money saved by Neil

we know that

x=y+258-------> equation 1

x/y=(7/4)-------> equation 2

substitute equation 1 in equation 2

(y+258) /y=7/4--------> 4*(y+258)=7*y------> 4y+1032=7y
