The legs of a right triangle measure 5√2 cm and 4√2 cm. find the area.

10√2 sq. cm
20 sq. cm
20√2 sq. cm

The answer is (b) 20 sq. cm.

Step-by-step explanation:  As given in the question and shown in the attached figure, ABC is a right-angled triangle with ∠ABC = 90°, the legs AB = 4√2 cm and BC = 5√2 cm.

We are to calculate the area of ΔABC.

Since AB is perpendicular to BC, so AB will be height and BC will be the base of the triangle.

Therefore, area of ΔABC is

Thus, the correct option is (b) 20 sq. cm.

a) 32pie square meters

step-by-step explanation:

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested

^ means raise to the power of
