Answer:
Step-by-step explanation:
2. Area of parallelogram = base*height
A = 24*9
A = 216
3. Surface area of prism = 2(wl + hl + hw)
l = 15 , w = 3 and h = 4
2(3*15+4*15+4*3)
2(45+60+12)
2(117)
234
Surface area of rectangular prism is 234mm^2
Answer:
1. 1/4 or 0.25 2.0.75
Step-by-step explanation:
D. DOQ & BOQ together equals 90 degrees
Answer:
Perimeter ratio = 2:1
Area ratio = 4:1
Step-by-step explanation:
<u>Perimeter</u>
Perimeter of the smaller photo =
inches
Perimeter of larger photo =
inches
Ratio:
Perimeter of larger photo : perimeter of smaller photo =
<u>Area</u>
Area of smaller photo =
inches²
Area of larger photo =
inches ²
Ratio
Area of larger photo : area of smaller photo =
∴The ratio of the perimeters = 2:1, and the ratio of the areas = 4:1
