Question

89 POINTS PLEASE HELP 7TH GRADE MATH... I WILL NOT SEND TOE PICS

Answer 1

Answer:1) 9*13=117

2)1/2*14(9+15)=168

3)1/2*18*11=99

Answer 2

1. This is a parallelogram. For parallelograms the formula for area is A = bh (b = base; h = height). Below is a picture that labels the base and height of this problem

h = 9 in

b = 13 in

so...

A = 9 × 13

A = 117

2. This is a trapezoid . For trapezoid the formula for area is A = $\frac{1}{2}h(b_{1} +b_{2} )$ (h = height; $b_{1}$ = base one; $b_{2}$ = base two). Below is a picture that labels the bases and height of this problem

h = 14

$b_{1}$ = 9

$b_{2}$ = 15

so...

$A = \frac{1}{2}14(9 + 15 )$

A = 7(24)

A = 168

3. This is a rhombus. For rhombus the formula for area is A = $\frac{1}{2}(d_{1} * d_{2} )$ ($d_{1}$ = diagonal one; $d_{2}$ = diagonal two). Below is a picture that labels the bases and height of this problem

$d_{1}$ = 11

$b_{2}$ = 18

so...

$A = \frac{1}{2}(11*18)$

A = $\frac{1}{2} (198)$

A = 99

Hope this helped!
