A=L*W
L=W+5
A=(W+5)W
500=W²+5W
W²+5W-500=0
W=(-5+/-√(25+4*500))/2=(-5+/-√2025)/2=(-5+/-45)/2
we are going to take only positive value, so W=(-5+45)/2=20
L=W+5=20+5=25
W=20,
L=25
Answer:
Step-by-step explanation:
divide 60% divided by 40 and then X five
X = 1/cos(30)
X = 1.154700538
X = 1.2 (nearest tenth)
Answer:
20 feet squared
Step-by-step explanation:
Dividing figure into a square and a triangle:
Area of square= 4x4=16 ft^2
Area of triangle=bxh/2=(2x4)/2=4 ft^2
Area of figure=16+4=20 ft^2
