What is the area of A is 7.7ft and B is 5.2ft and C is 9.29 and this is a triangle

1 answer:

8 0

First find half of the perimeter of the triangle: s = (a + b + c) / 2 = 11.095

Then the area is:

A = Square Root [11.095 (11.095 - 7.7)(11.095 - 5.2)(11.095 - 9.29)] = 20.01999895 or 20.02 square feet rounded to 2 decimal places.

Answer:

a) Simple interest paid = $360

b) Total repayment amount = $6360

Step-by-step explanation:

It is given that:

Principal, P = $6000

Rate of interest, R = 2%

Time, T = 3 years

(a) Total interest paid:

Formula for Simple Interest is given as:

$S.I. = \dfrac{P \times R \times T}{100}$

Putting the values of P, R and T to find out Simple Interest: $\\\Rightarrow S.I. = \dfrac{6000 \times 2 \times 3}{100}\\\Rightarrow S.I. = \$360$

(b) Total repayment amount:

We know that formula for total amount is given as:

Amount = Principal + Simple Interest

Amount = 6000 + 360 = $6360

So, total repayment amount = $6360

So, the answers are:

a) Simple interest paid = $360

b) Total repayment amount = $6360
