Suppose the zeroes are a , b so
Answer:
See below ~
Step-by-step explanation:
For the question with colored rectangles, it asks to find the area.
The area can be found by multiplying the dimensions of the rectangle.
Blue rectangle :
- A = 10 ft. x 6 ft.
- A = <u>60 ft²</u>
<u></u>
Green rectangle :
- A = 12 cm. x 8 cm.
- A = <u>96 cm²</u>
<u></u>
Question 13 :
- Here, we are given 2 rows and 7 columns
- Take them as the dimensions
- Hence, area = 2 x 7 = <u>14 square units</u>
Answer:
41 feet
Step-by-step explanation:
We apply the theorem below:
If two similar triangles have a scale factor of a : b, then the ratio of their perimeters is a : b.
Let x be the perimeter of the smaller triangle
If the ratio of their heights is 6:5 and the perimeter of the larger triangle is 49.2 feet,
6:5=49.2:x
6/5=49.2/x
Cross multiplying
6x=49.2 X 5
6x=246
x=246/6=41
The perimeter of the smaller triangle is 41 feet
