Answer:
I believe it is the second answer.
The area of a triangle is 1/2(base x height) .
The two legs of this triangle are equal. If you position it properly,
one of them is the base, and the other one is the height.
Since it's a right triangle, A² + B² = C²
But A = B and C = 24 .
2A² = (24)²
A² = (24)² / 2
But since A=B, A² is also (base x height) of the triangle.
Area is just 1/2 of it.
Area = 1/2(24²/2) = (24)²/4 = (24/2)² = (12)² = <u>144</u> .
Answer:
Breadth is 25% of the length
Step-by-step explanation:
Length, l = 24 cm
Breadth, b = 6cm
Expressing the breadth as a percentage of the length :
(Breadth / length) * 100%
(6 / 24) * 100%
0.25 * 100%
= 25%
Hence, the breadth is 25% of the length
