What is the area of this trapezoid?

153squared

Step-by-step explanation:

The two triangles on the side have an area of 63.

The rectangle has an area of 90.

90+63=153

153 ft²

Step-by-step explanation:

Area of a triangle: 1/2 bh

                              1/2 (7x9)

                              1/2 (63)

                              31.5

Since there are two triangles of the same size: 31.5x2=63

Area of a rectangle: lw

                                  (9x10)

                                  90

Add them together:

  63+90=153

i agree because i see the other persons thinking is clear

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
