Answer:
80 sq units
Step-by-step explanation:
Starting with the largest rectangle, we see it has a width of 6 and a length of 8, meaning the area of that only is 48 sq units. (area of rect. = l x w, so 6 x 8 is 48)
There are two smaller rectangles with width 6 and length 2. One of those rectangles would be 12 units (6 x 2). Since there is two of them, then 24 sq. units.
Lastly, there are four small triangles. The area formula for a triangle is 1/2(b)(h). The triangle has a base of 2 and a height of 2. (1/2)(2)(2) =2. Since there are four triangles, the total for them only would be 8 (2 x 4).
Adding each of these pieces together will give us the answer:
48+24+8=80 sq units
Answer:
Area =
Step-by-step explanation:
We let the width of the pool be "w"
We know the length is twice as long as width, so the length is:
2w
So,
Width = w
Length = 2w
Since a sidewalk with 2 feet width goes around the pool completely, the area enclosed by pool + sidewalk would have 2 feet around it, so its length and width would be:
Width = w + 2 + 2 = w + 4
Length = 2w + 2 + 2 = 2w + 4
The area of a rectangular region is always length * width, so the expression for area of pool and sidewalk would be:
If we let the width of the swimming pool be "w", the expression for the area of pool and sidewalk is:
Area =
Answer:
400 ft
Step-by-step explanation:
The building's shadow is 10 times the length of the flagpole's shadow. Since the shadow length is proportional to the object height, the building must be 10 times the height of the flagpole, so is 400 ft tall.
The area of this right triangle would be 33 ft
