Answer:
The new length is 13.5 meters
Step-by-step explanation:
Here, we are interested in calculating the new length of the cloth she wants to use
What we know from the question is that she is making a reduction of 10% from an initial of 15 meters
Thus, the length she is to use can be calculated by first getting what 10% of 15 meters is
Mathematically, that would be ;
10/100 * 15 = 1.5 meters
We now subtract this from the total of 15 meters
= 15 meters - 1.5 meters = 13.5 meters
There's no problem there??
A = 1/2 * (b1 + b2) * h
b1 and b2 are the lengths of the bases of the trapezoid
h is the height
Answer:
30%
Step-by-step explanation:
If 2400$=100%
1680$=?
100×1680$÷2400$=70%
