Answer:
see below
Step-by-step explanation:
1a) Area of rectangle = L * W
A = 57*35 = 1995 in²
1b) A =L * W = 8 * 14.3 = 114.4 cm²
1c) Area of Δ =1/2 base x height
Height is always perpendicular to the base!!!
base = 36; height = 15
A of Δ = (1/2) * 36 * 15 =18*15 = 270 m²
1d) Area of Δ =1/2 base x height
base = 27.3; height = 16.8
A of Δ = (1/2) * 27.3 * 16.8 = 229.32 rounded to final answer 229.3 in² !!!!
1e) Area of Δ =1/2 base x height
base = 14; height = 9
A of Δ = (1/2) * 14 * 9 = 7 * 9 = 63 yd²
1e) Area of Δ =1/2 base x height
base =30 ; height = 40
In this case base also can be 40 and height 30 b/c it's right Δ
A of Δ = (1/2) * 30 * 40 = 15 * 40 =600 ft²
