Answer:
135 mm²
Explanation:
Rectangles A B C D and U R S T are congruent. The length of sides A B is 9 millimeters and the length of sides R S is 15 millimeters.
What is the area of rectangle URST?
Answer: Two rectangles are said to be congruent if the size of their sides are equal. If Rectangles A B C D and U R S T are congruent, this means that AB = UR, BC = RS, CD = ST and AD = UR
Given that:
AB = 9 millimeters and the length of sides RS = 15 millimeters.
Area of rectangle URST = length × breadth = UR × RS
but since ABCD and URST are congruent, UR = AB. Therefore:
Area of rectangle URST = length × breadth = AB × RS = 9 mm × 15 mm = 135 mm²
