Sum of adjacent angles on a straight line is 180°
x+56°=180°...
x=180°-56°
x=124°

Answer: 82 ft squared
Step-by-step explanation: The surface area is 2( wl + hl + hw)
so the width is 2 the length is 7 and the height is 3
so it's 2( 14 + 21 + 6) = 2(41) = 82
Step-by-step explanation:
1. solution,
length of rectangle A(l)=3.1units
breadth of rectangle A(b)=1units
now,
area of rectangle A=l×b
=3.1units×1units
=3.1 sq units
2.solution,
length of rectangle B(l)=3.1units
breadth of rectangle B (b)=0.4units
now,
area of rectangleB=l×b
=3.1units×0.4units
=1.24 sq units
3.solution,
length=3.1units
breadth=1.4units
area =lxb
=3.1units x 1.4units
=4.34units
