Question

ABC is a triangle in which AB = AC = 4 cm
and angelA = 90°. Calculate :
(i) the area of A ABC,
(ii) the length of perpendicular from A to BC.​

Answer 1

the answer of the 2nd part of the question

Answer 2

Answer:

area of triangle is half of length into breadth

length is 4 and bredth is 4

hence area is 8cm^2

Step-by-step explanation:

ii) the length of hypotenuse bc is root 32.

now let's consider the triangle as a square. to find the diagonal of square multiply the length of its side to root √2. since the length of perpendicular from a to bc will be half the diagonal of the square the answer is 2.82
