Answer:
area = 32 in²
Step-by-step explanation:
the area (A) of a triangle is
A = bh ( b is the base and h the perpendicular height )
here b = 8 and h = 8, hence
A = × 8 × 8 = 32 in²
Answer:
Step-by-step explanation:
Width =x
Length = 2*x = 2x
Diagonal = 5√5
Use Pythagorean theorem
Length² + Width² = diagonal²
(2x)² + x² = (5√5)²
{}
4x² + x² = 75
5x² = 75
x² = 75/5
x² = 15
x = √15
Width = √15
Length = 2√15
Area of rectangle = length *width
= √15 *2√15
= 30 square units
