Area if a Triangle formula
A = 1/2 b h
A = 1/2(21)(8)
A = 1/2(168)
A = 168 / 2
A = 84

Area of Triangle = 1/2 * base * height
1/2 * 21 inches * 8 inches
Area = 84 inches^2

base = 21 inches
height = 8 inches
the area of a triangle = 1/2 bh
= 1/2*21*8
= 21*4
= 84 inches

Area = (1/2) x 21 x 8 in²
Area = 4 x 21 in²
Area = 84 in²

Area of a right triangle (with one corner 90 degrees) is:
A = 1/2 b x h = .5(21)(8) = 84 inches

OK
a= b x 1/2h
a = 21 x 8/2 =84 In²

i would be surprised if everybody solutions this many questions. My suggestion, ruin it right into a team of separate posts & do no longer difficulty exhibiting the question extensive variety or means solutions (people will in basic terms wager in case you supply them options). and don't enter all of them in a row, unfold them out approximately 5 minutes aside. i will answer one to get you all started 24. Perimeter = all 4 factors further jointly = 11 + 3 + 11 + 3 = 28 inches
