Question

Plz answer this question with full method and formulates.

Answer 1

If each dot to dot length is 1 cm then according to Pythagorean the diagonal dots length is:-

whole root 1^2+1^2 = whole root 1+1=root 2

in AC there are 3 such diagonal dots hence AC=3√2

AB also is 2√2

BC is √2 according to Pythagorean theorem

SO applying the formula

1/2 x b x h we get

1/2 x √2 x 2√2

2
