4. 289.
5. 632.
Step-by-step explanation:
The key to doing these is to split the polygons into rectangles, triangles or trapezoids as appropriate.
For example, number 1 consists of a rectangle area 8 * 8 and another of 3* 2.
So the area = 64 + 6 = 70 unit^2.
2. The area = sum of 3 rectangles 1*1 + 4*6 + 2*2.
3. Area = 11*15 + 11*15 + 1/2*15*15
4. Area = 18*12 + 1/2 * 6 * 15 + 1/2 * 7 * 8.
5. Area = area of 2 rectangles + area of a trapezoid.
= 18 * 24 + 4*10 + 1/2(12 + 20) * 10.
Answer:
Randy just added up the numbers on the numerator and denominator.
This is incorrect.
<u>Correct way of adding the fractions given below:</u>
- 7/8 + 9/15 = ⇒ Simplify the second equation, divide by 3)
- 7/8 + 3/5 =
- 5*7/5*8 + 8*3/8*5 = ⇒ Bring both fractions to common denominator of 40
- 35/40 + 24/40 = ⇒ Add up the numbers in the nominator
- 54/40 = ⇒ Simplify by dividing by 2
- 27/20 =
- 1 7/20 ⇒ Convert to mixed fraction

Answer:
Calculate the unknown defining height, slant height, surface area, side length and volume of a square pyramid with any 2 known variables. ... e = lateral edge length r = a/2. V = volume. L = lateral surface area. B = base surface area The units are in place to give an indication of the order of the results such as ft, ft2 or ft3.
