Answer:

(a + b)² = 35

Step-by-step explanation:

Note the expansion of (a + b)²

(a + b)² = a² + b² + 2ab ← substitute given values

            = 25 + 2(5)

            = 25 + 10

            = 35

Identify the lateral area and surface area of a regular square pyramid with base edge length 11 cm and slant height 15 cm, round
Ann [662]

The surface area of the square pyramid is: 451 cm²

The lateral surface area of the square pyramid = 330 cm²

<h3>What is the Lateral Surface Area and Surface Area of a Square Pyramid?</h3>

Surface area = a² + 2al, where a is the base edge and l is the slant height.

Lateral Surface Area =  2al.

Given the following:

  • a = 11 cm
  • l = 15 cm

Surface area = a² + 2al = 11² + 2(11)(15)

Surface area = 451 cm²

Lateral Surface Area =  2al = 2(11)(15)

Lateral Surface Area = 330 cm²
