Answer:
Step-by-step explanation:
Perpendicular height will split the base into two equal parts.
Use Pythagorean theorem,
hypotenuse² = base² + altitude²
= 28² + 45²
= 784 + 2025
= 2809
hypotenuse = √2809 = √53 * 53 = 53 mm
Perimeter = 53 + 53 + 56 = 162mm
Answer:
Step-by-step explanation:
each side of smaller triangle = √(28²+45²) = 53 mm
(larger base)/(smaller base) = 168/56 = 3
each side of larger triangle = 3×53 = 159
perimeter of larger triangle = 159+159+168 = 486 mm
