Answer:
100 m²
Step-by-step explanation:
The scale drawing has dimensions 25 cm and 16 cm
The actual rectangles dimensions are 50 times greater, that is
length = 25 × 50 = 1250 cm ← divide by 100 to convert to m
length = 1250 ÷ 100 = 12.5 m
width = 16 × 50 = 800 cm
width = 800 ÷ 100 = 8 m
Actual area = 12.5 × 8 = 100 m²
Answer:
25
Step-by-step explanation:
(-5)^2+10(-5)(2)+25(2)^2
=25+(-100)+100
=25
We use the Pythagorean theorem to determine if the side lengths given will result to either a right, acute, or obtuse triangle.
a = 7 ; b = 24 ; c = 26
a² + b² = c² ⇒ right triangle
a² + b² > c² ⇒ acute triangle
a² + b² < c² ⇒ obtuse triangle
7² + 24² = > < 26²
49 + 576 = > < 676
625 < 676 OBTUSE TRIANGLE
In standard form:
800+200
=1,000
