The answer please answer

Step-by-step explanation:

Area of trapezoid

= 1/2 × 4 × [6 + (5+8)]

= 1/2 × 4 × 19

= 38 cm²

y=mx+b

step-by-step explanation:

m slope

b y-intercept

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
