Answer:
31 cm
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A =
h (a + b)
where h is the height and a, b the bases
Here A = 162, h = 6 and a = 23 , then
× 6 (23 + b) = 162
3(23 + b) = 162 ( divide both sides by 3 )
23 + b = 54 ( subtract 23 from both sides )
b = 31
The other base is 31 cm
B. Quadrant 3
The top left corner is quadrant 1 then the top right corner is quadrant 2 then the bottom right corner is quad 3
