Answer 1

Step-by-step explanation:

Two sides of triangle are 2a 2

Two sides of triangle are 2a 2 +3a+2 and 3a 2−4a−1

Two sides of triangle are 2a 2 +3a+2 and 3a 2−4a−1Let the third side be s

Two sides of triangle are 2a 2 +3a+2 and 3a 2−4a−1Let the third side be sPerimeter=8+13a+7a 2 =2a 2 +3a+2+3a 2 −4−1+s

Two sides of triangle are 2a 2 +3a+2 and 3a 2−4a−1Let the third side be sPerimeter=8+13a+7a 2 =2a 2 +3a+2+3a 2 −4−1+s⟹s=2a

Two sides of triangle are 2a 2 +3a+2 and 3a 2−4a−1Let the third side be sPerimeter=8+13a+7a 2 =2a 2 +3a+2+3a 2 −4−1+s⟹s=2a 2

Two sides of triangle are 2a 2 +3a+2 and 3a 2−4a−1Let the third side be sPerimeter=8+13a+7a 2 =2a 2 +3a+2+3a 2 −4−1+s⟹s=2a 2 +15a+7

Two sides of triangle are 2a 2 +3a+2 and 3a 2−4a−1Let the third side be sPerimeter=8+13a+7a 2 =2a 2 +3a+2+3a 2 −4−1+s⟹s=2a 2 +15a+7So, the third side of triangle is =2a

Two sides of triangle are 2a 2 +3a+2 and 3a 2−4a−1Let the third side be sPerimeter=8+13a+7a 2 =2a 2 +3a+2+3a 2 −4−1+s⟹s=2a 2 +15a+7So, the third side of triangle is =2a 2

Two sides of triangle are 2a 2 +3a+2 and 3a 2−4a−1Let the third side be sPerimeter=8+13a+7a 2 =2a 2 +3a+2+3a 2 −4−1+s⟹s=2a 2 +15a+7So, the third side of triangle is =2a 2 +15a+7
