Answer:
440cm³
Step-by-step explanation:
Area of trapezium base=
Volume=Area or trapezium x Height between trapezium ends
10 inches because there are 4 sides of a square so, if the perimeter is 40 inches, to figure out the side lengths you just have to divide the perimeter by 4
Answer:
Step-by-step explanation:
l -> length
b -> width
h -> height
Find the area of four walls and ceiling. then subtract the area of four windows and a door form that area.
Area of four walls + <u>ceiling</u> = 2( lh + bh) +<u>lb</u>
= 2*(20*5 + 15*5) + 20*15
= 2( 100 + 75) + 300
= 2* 175 + 300
= 350 +300
= 650 sq m
Area of window = 2 *3 = 6 sq.m
Area of four windows = 4*6 = 24 sq.m
Area of door = 2 * 1 = 2 sq.m
Area of four walls excluding 4 windows and door = 650 - 24 - 2 = 624 sq.m
Cost of painting = 624 * 6.50
= $ 4056
Answer:
12 meter
Step-by-step explanation:
We know that ,
Area of rectangle = length × breadth
so,44m square = l × 3 2/3 m
or, 44m2 = length × 11/3
or ,( 44m2)/3 2/3m = length
finally, length = 12 meters
