Answer: 3.15 mm²
Step-by-step explanation:
First, we multiply the height by the base: 4.2 x 1.5 = 6.3
But, since this is a triangle, we have to divide this number by 2: 6.3 / 2 = 3.15
Hope this helps you!
5.45787878 = 545787878/100000000
divide both numerator and denominator by 2 or any other number
545787878 ÷ 2 = 272893939
100000000 ÷ 2 = 50000000
272893939/50000000 is your answer

Answer:
Option C. 
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor and the ratio of its perimeter is equal to the scale factor too
step 1
Find the width of the rectangle that has a length of 4 feet and a perimeter of 14 feet
The perimeter of a rectangle is equal to

substitute the values and solve for W


step 2
Find the scale factor
Let
z-----> the scale factor
To find the scale factor divide the width of the larger rectangle by the width of the smaller rectangle
so

step 3
Find the perimeter of the larger rectangle
To find the perimeter of the larger rectangle multiply the perimeter of the smaller rectangle by the scale factor
so
