The area of a triangle varies jointly with the height of the triangle and the length of its base. the area of one triangle is 200 square centimeters when its height is 25 centimeters and its base length is 16 centimeters. what is the area of a triangle having a height of 20 centimeters and a base length of 15 centimeters?

multiply the length by the width.

Step-by-step explanation:

.

step-by-step explanation:

.

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
